Description

[Detailed Description of the Invention] The present invention relates to a running toy equipped with a drive mechanism using a mainspring as a power source, and particularly to a toy that is accompanied by an action that transforms the toy body during running.

Conventionally, among traveling toys equipped with a drive mechanism consisting of a gear device linked to wheels and a mainspring serving as a power source, the toy body is moved backward to rotate the drive wheel and store energy in the mainspring. It is known that when you let go of your hand, the energy stored in the mainspring rotates the drive wheels and propels itself.

Although various types of play are possible with such a traveling toy, there are few surprises because the shape of the toy itself does not change. By the way, adding surprises to toys can double the fun of traditional ways to play with them, and
It also develops into the creation of new ways of playing.

This invention was made in view of these points,
To provide a traveling toy which is in a locked state when energy is stored and is released when traveling is driven to elongate and deform the toy body, and travels while exhibiting unexpectedness in shape change.

In addition to the extension of the main body 10, an exhaust pipe 60 as described below
The spring receiving member 23 has such a structure because the function of vertical movement is added to the front chassis 11.
The spring receiving piece 231 may be directly protruded from a suitable position on the bottom surface of the housing.

A drive mechanism 30 mounted on the rear chassis 12
consists of a mainspring and a gear device (both not shown) installed in a machine frame 31, and an axle 17 linked to the gear device is rotatably mounted horizontally at a suitable position under the machine frame 31. It is constructed by attaching a rear wheel 18. When the rear wheel 18 is forcibly rotated in the backward direction of the main body 10, the mainspring is wound and stores energy through a gear system, and when the rear wheel 18 is freed, it rotates the rear wheel 18 through the gear system. drive This causes the toy main body 10 to travel. Note that the machine frame 31 is configured to also accommodate a lock release means 50, which will be described later.

Locking means 40 for locking the extension of the toy body 10
As shown in FIG. 3, a locking arm 41 is rotatably supported at an appropriate position on the side of the machine frame 31;
A spring 45 has one end fixed at a proper position on the machine frame 31 to bias the locking arm 41 and maintain the locked state; 41 and a locking protrusion 46 that engages with the tip 44 of the locking member 41. The locking arm 41 is formed into a substantially L-shape, and its base end is rotatably attached to the machine frame 31. Also, arm 41
On the machine frame 31 side of the bent portion, there are provided an abutment piece 42 with which a cam of a lock release means 50 (to be described later) comes into contact, and a connection piece 43 that connects the movable end of the spring 45. The spring 45 urges the locking arm 41 to rotate counterclockwise in the figure, and when the front chassis 11 and rear chassis 12 are fitted together, the arm 41 automatically rotates. Then, the tip 44 and the locking protrusion 46 are engaged and held in this state. Note that the lower surface side of the end of the contact piece 42 is
The taper is provided so that the cam can slide against the lower surface of the corresponding contact piece 42 and easily push it up when the lock is released.

Lock release means 50 acting on the locking means 40
As shown in FIG. 3, the gear device 51 is provided adjacent to the drive mechanism 30 in the machine frame 31 and extracts power from a part of the gear device of the drive mechanism 30; a cam 52 which is rotated by the cam 51 and pushes up the abutment piece 42 of the locking arm 41;
The cam 52 is located between the gear device 51 and the cam 52, and controls only the rotation of the rear wheel 18 during driving.
and a one-way clutch 53 for transmitting power to the vehicle. The cam 52 is provided with a protrusion on the outer periphery of the follower side of the one-way clutch 53 so that the clutch 53
Although it is provided integrally with the above, it may of course be constructed separately. This cam 52 is disposed so as to contact the base side of the abutting piece 42 when the mainspring is energized, and to abut the tip end side of the abutting piece 42 when driving the mainspring, and the torque acting on the locking arm 41 is It makes a difference.

In the one-way clutch 53, when the mainspring is energized, the cam 52 comes into contact with the contact piece 42 and is locked, so the follower side slips and becomes disengaged. Therefore, since no further rotational force is applied to the cam 52, it remains in this state and does not push up the locking arm 41. At this time, the follower side end of the clutch 53 is urged by the spring piece 32 provided on the side surface of the machine frame 31 so as to return to the engaged state. On the other hand, during driving, the one-way clutch 53 does not disengage, so power from the gear device 51 is applied to the cam 52 to rotate it. cam 5
2 presses the contact piece 42 in response to this rotational force,
Push up the locking arm 41. The timing of pushing up can be determined as appropriate by selecting the ratio of the number of teeth of the gear device 51.

Note that in this example, a one-way clutch was used as a means for transmitting rotational motion in only one direction.
Other means may also be used, such as ratcheting.

Next, an example of assembling the traveling toy of the present invention will be explained.

First, the front wheel 16 is attached to the front chassis 11 by horizontally suspending the axle 15, and then the spring receiving member 23 is attached to the front chassis 11.
The shaft 232 is rotatably mounted on the bearing 111,
The front body 13 is attached to the upper part of the chassis 11 by screwing or other means. A portion of the body 13 contacts the pressing piece 233 of the spring receiving member 23, and prevents the pressing piece 233 from rotating upward.

On the other hand, on the rear chassis 12, a locking means 40 and a locking release means 50 are installed on the machine frame 31, and a drive mechanism 30 to which the rear wheel 18 is attached is mounted.
It is fixed with a locking pawl 128 or the like, and the rear body 14 is attached thereon by screwing or other means.

Next, the spring 21 is attached to the spring accommodating portion 22, placed on the bottom plate 113 of the front chassis 11, the front and rear chassis 11 and 12 are brought close together, and the bottom plate 113 is inserted into the opening 123 of the rear chassis 11. , the side plates 112, 112 are placed on the support protrusion 122, and the chassis 11, 12 are placed in the locking groove 11.
6 and 6 until the locking pawl 126 engages with the
These are fitted and connected. (See Figure 4). In this state, the main body 10 is extended and the front and rear parts of the body are separated, so the chassis 11 and 12 are
Press further against the pressure of step 1 to bring the front and rear parts into contact. At this time, the spring 21 is compressed.
Further, the locking arm 41 of the locking means 40 is biased by the spring 45, and the tip 44 engages with the locking protrusion 46 on the front chassis 11 side, as shown in FIG. Lock extension.

Next, the operation of the traveling toy of the present invention assembled as described above will be explained.

First, the user holds the toy main body 10 in his hand and moves it backwards on the running surface to rotate the rear wheel 18 and store energy in the mainspring of the drive mechanism 30. At this time,
In the lock release mechanism 50, the cam 52 rotates slightly due to the rotation of the gear device 51, but comes into contact with the base of the contact piece 42 of the lock arm 41. Here, the gear device 51 attempts to further rotate the cam 52, but since the one-way clutch 53 interposed between the two disengages, the cam 52 remains in contact with the contact piece 42. state, and the locking arm 41 is not pushed up. Therefore, the extension of the main body 10 is maintained in a locked state (see FIG. 6A).

Next, when the user releases the main body 10, the rear wheel 18 is driven and rotated by the power from the mainspring, and the main body 10 starts running. As a result, the cam 52 that was in contact with the contact piece 42 is rotated by the rotational force from the gear device 51 in the opposite direction to that at the time of storing energy.
Then, it comes into contact with the contact piece 42 again after a little less than one rotation (see FIG. 6B), but at this time, since the one-way clutch 53 is not disengaged, torque continues to be applied to the cam 52. Therefore, the cam 52 slides into contact with the lower end of the contact piece 42 and gradually pushes it up.
Finally, it reaches the lower surface of the contact piece 42, pushes it up and rotates. As a result, the locking arm 41 is pushed up against the tension of the spring 45, and its tip 44
is removed from the locking protrusion 46.

Due to this unlocking, the compressed spring 21 of the biasing means 20 expands while pressing the spring receiving pieces 221 and 231, and pushes the front part of the main body 10 forward. As a result, this traveling toy travels with the main body 10 being elongated and deformed in the longitudinal direction as shown in FIG. 5B. Note that, as shown in FIG. 4, the front chassis 11 and the rear chassis 12 are locked by the locking pawl 126 engaging with the end of the locking groove 116, so that the connection will not come off when they are extended. There isn't.

Furthermore, the traveling toy of this embodiment is equipped with a mechanism for locking the extension motion, and can also be played with as a normal traveling toy. Locking is performed by operating a switching lever 124 protruding from the lower surface of the rear chassis 12 and engaging a locking hook 125 with a hook locking portion 115 provided on the front chassis 11.

Next, an example will be described in which the function of moving the exhaust pipe up and down is added to the above embodiment.

As shown in FIG. 7A, the exhaust pipe 60 has a shaft 61 at its base and a pressing piece 233 of the spring receiving member 23.
and a contact portion 62 that comes into contact with the contact portion 62. On the other hand, the front chassis 11 to which this exhaust pipe 60 is attached has
As shown in FIG. 2, a notch 117 is provided at the rear of the front wheels on the left and right side surfaces, and a bearing 11 rotatably supports the shaft 61 around the notch 117.
8 will be provided.

When assembling the front part of the main body 10 when it has this exhaust pipe 60, first, the bearing 118 of the front chassis 11 is assembled.
The shaft 61 is attached to the exhaust pipe 60, and then the spring receiving member 23 and the body 13 are attached according to the procedure described above. Then, it is connected to the rear part of the main body 10 assembled in the above-mentioned procedure, and further, the main body 1
Press around 0 to completely integrate. At this time, the exhaust pipe 60 is connected to the rear body 1 as shown in FIG.
4 and is in a state of being pushed down (see FIG. 7A).

When the toy of this embodiment is run in this state, the main body 10 is extended by the above-described operation and the rear body 14 is separated from the exhaust pipe 60, so that the exhaust pipe 60 becomes rotatable. On the other hand, inside the front chassis 11, the spring receiving piece 231 of the spring receiving member 23 is pressed by the spring 21 to generate torque, so the pressing piece 233 presses the contact portion 62 downward. Then, when the exhaust pipe 60 becomes rotatable as described above, the pressing piece 233 presses down the contact portion 62. Therefore, the exhaust pipe 60 rotates about the shaft 61,
It changes to the lifted state as shown in FIG. 7B.

As described above, according to this embodiment, not only the elongation of the main body but also the vertical change of the exhaust pipe can be added, and a sufficient degree of surprise can be achieved. In the above embodiment, a case where the present invention is applied to a car is shown, but the present invention can be applied to various types of traveling toys, and each can exhibit its own unique unexpectedness. For example, it can be applied to vehicle toys such as airplanes and ships, war toys such as tanks, animals, insects, robots, etc.

As explained above, the present invention divides the main body of the toy into two parts, connects the toy main body in an expandable manner, and includes a biasing means for extending the main body, a means for locking the extension, and a means for releasing the locking. The toy body is configured to be in a locked state when the energy is stored, and to be released when the toy is driven to extend and deform the toy body.
It has the effect of doubling the fun of the toy by adding the unexpectedness of shape changes to the normal running.
